Description
Invention field
The present invention relates to comprise the compatible blend of high and low unsaturated elastic body.
Background
Mainly due to their property, as excellent in resistance ozone degradation and cracked performance, improved chemically-resistant etch, improved temperature stability and unique dynamic response subsequently, be interesting in rubber industry based on vulcanized rubber low or that do not have olefinic unsaturated elastic body and a blend of higher unsaturated elastic body.These blends make and produce synergy between single elastomericss, obtain the composite blend performance combination that can not reach in single elastomerics.But these desired properties only occur under following situation: produce in blend and keep phase size less than 5 microns, general 1 micron or littler elastomerics be even blend closely, and has reached gratifying interfacial adhesion level.
Lamentedly, general knownly can not overcome the unfavorable entropy of blended because the favourable entropy of blended is too little, make and mix unfavorablely, unless have specific, favourable interaction, most polymers is also incompatible each other.Diameter dimension very inhomogeneous by the blend of routine techniques production and phase is many microns.When the solubility parameter of single polymkeric substance significantly not simultaneously, this of single polymkeric substance very uncompatibility and the consequent is obvious especially to producing and keeping required uniform, the powerless of fine phase size.This is the situation in the time will hanging down unsaturated elastic body and higher unsaturated elastic body blend.
Adopt another problem of saturated-unsaturated elastic body mixture to be that even high shear mixing produces tight dispersion, mixture is separated into blend thereafter, this blend is that the diameter dimension of very uneven and single phase is many microns.These very uneven blends generally have the performance combination of non-constant, and are poorer than single polymkeric substance usually, rather than show from phase size less than 5 microns general 1 micron or the littler closely evenly desired properties combination of blend.
A kind of scheme for the incompatible polymer consistency is blend in segmented copolymer, this segmented copolymer comprise derived from the monomeric segment of blend polymer-compatible and derived from monomeric another segment of another kind of blend polymer-compatible.For example, EP691378A discloses the blend polymer that comprises polycarbonate resin and polyisobutene, and this blend is compatible by comprise a small amount of polycarbonate-polyisobutylene block copolymer in blend composition.In addition, U.S. patent No.5,741,859 disclose the segmented copolymer of polyisobutene and polydimethylsiloxane and have advised that they are used as the purposes of compatilizer.

Polym.Mater.Sci.Eng., 63, the 371-375 page or leaf is disclosed as compatilizer in 1990.
The blend polymer that comprises the mixture of isobutene polymer and Geng Gao unsaturated elastic body such as polyhutadiene or polyisoprene is potential ozone proof, chemicals-resistant, gastight and temperature-stable as mentioned above.But the multipolymer of isobutene polymer such as polyisobutene, iso-butylene and isoprene (isoprene-isobutylene rubber), iso-butylene and to the multipolymer of ring-alkylated styrenes and their halogenation variant not with higher unsaturated elastic body as polymer-compatible based on conjugated diene monomer.In the presence of specific, extensive chemical interacted not, these different polymkeric substance had the positive free energy of mixing and are that thermodynamics is inconsistent therefore, and this is because mixture heat is normally positive less with the entropy that obtains when mixing these different polymer molecules.The result is bonding and because the weak blend mechanical property of shortage attach structure form of high interfacial tension and the difference between two blends phases.The present invention relates to by the height of introducing segmented copolymer and the improvement blend of low unsaturated elastic body.

vAccording to table 2 data, in the size that reduces PIMS trace phase, tbS-iB-tbS is obvious to the compatible effect of PIMS/Budene 1207 and PIMS/Natsyn 2200 blends.Equally, in the presence of tbS-iB-tbS, the PIMS phase size in PIMS/Natsyn 2200 blends reduces than more in PIMS/Budene 1207 blends.This is consistent with following observation situation: the tbS homopolymer is more compatible with polyhutadiene with the polyisoprene ratio.The observation form factor that reduces in comprising two kinds of blends of tbS-iB-tbS reflects the more non-sphere and the PIMS territory of high surface area more.This long-pending increase of the field surface of per unit volume shows because the existence of tbS-iB-tbS compatilizer, is used to hinder the spatial stability of the reduction of PIMS phase coalescence and/or interfacial tension in these blends.
